Verified record
Reliable Air is a Lowell, Massachusetts air conditioning business; a 2017 review said Paul Adams runs it. Its written record runs from 2015 to 2020. In a 2015 review, a customer accused the business of stealing an air conditioner circuit board and said they believed it was out of business, calling it 'a hack' according to three other HVAC companies. Two later reviews, in 2018 and 2020, separately said there was no warranty for the work. The 2020 review also described an air conditioner installation that never worked right, with no receipt given; the reviewer said another company, Franks Heating and Air, later found and fixed the underlying problem. A 2017 review praised Paul Adams for correctly scoping an air conditioning job in a 10,000-square-foot historic home after six companies gave estimates, using the original duct work. Google shows a 2.3-star average from 6 ratings.
I would never recommend this company. I had an air conditioner installed by him and it hasn't worked right. He never gave me a receipt and never gave me a warranty. Buyer beware. After 2 years of finding out what the problem I was having Franks heating and air fixed it. The system was put in wrong. Cost me more money. Buyer BEWARE
No warranty for his service, Stay away
Paul Adams who runs reliable air is top notch. After inquiring with six local companies to give estimates for Air Conditioning in a 10,000 sq. ft historic home, Paul was the only one who scoped the job correctly and understood our request to use the original duct work and octopus furnace. The others wanted to cut through walls and use split air systems which would ruin the historic prestige of the property. Their estimates ranged from $17k - 60k, Paul did the work for a fraction of the cost and even allowed me to purchase the equipment needed. He showed up at the scheduled date and time and expertly installed the AC equipment. He cleaned everything and tested the unit throughout the whole house with me. The system runs flawlessly and their were no hidden costs in the final bill. We recently used Paul again to install a replacement water heater. Again he called right back set up a date, was there on time and did an excellent job. Again his rate was very fair and he cleaned up everything at the job site. He is very honest and straightforward and I would highly recommend him to anybody looking for these types of services. -- John Doherty
